Need to replace my Internet modem to gain speedier connectivity in my Lennar connected home. The old modem works fine connected to an ICS-7150-C12P which connects to an R510 WAP. When I change the modem, being careful to plug in everything as it was before, the SSID is viewable but will not deliver IP addresses to wireless clients. The new modem connects to the service provider and wired devices work just fine. For some reason, wireless connectivity is not working properly. I have no idea where to start looking. Any ideas or help would be appreciated.
